Borea BR02 features a 1" silk Tweeter and 1 x 5" fiberglass Woofer with a Crossover frequency at 2900Hz. On the other hand, the Borea BR04 features a 1" silk Dome Tweeter and 1 x 6" Paper Cone Woofer with a Crossover frequency at 3200Hz.
Frequency Response
Borea BR02 has a frequency range of 51 - 22k Hz whereas Borea BR04 has a frequency range of 44 - 22k Hz. With a minimum frequency of 44Hz, the Borea BR04 can go significantly deeper on the low side and provide stronger bass compared to the Borea BR02's min frequency of 51Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Borea BR02 and Borea BR04 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Borea BR02 sensitivity is rated at 89 dB and the Borea BR04's is at 90 dB. This 1 dB difference makes the Triangle Borea BR04 a more sensitive speaker compared to Triangle Borea BR02, hence will play louder with the same amount of watts.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using
an amplifier within this range ensures the nominal performance , inputting a power that is higher than the
max wattage can result in a damaged speaker.
Borea BR02 can handle a max power of 110 watts RMS from the amp the whereas Borea BR02 has a max power handling value of 80 watts RMS , 30 watts less than the Borea BR04.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Borea BR04 features Dual binding posts posts which make bi-amping or bi-wiring possible. Borea BR02 has a Binding post which doesn't feature bi-amping/bi-wiring.

Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Triangle Borea BR02's and Triangle Borea BR04's external dimensions. Triangle Borea BR02 has external dimensions of 310.0 x 176.0 x 274.0mm ( 12.2 x 6.9 x 10.7inch) whereas Triangle Borea BR04 has external dimensions of 425.0 x 220.0 x 314.0mm ( 16.7 x 8.7 x 12.3inch) .
Triangle Borea BR04 is clearly the larger of the two speakers. Its body is 44mm wider, 115mm taller and 40mm deeper than Triangle Borea BR02.
Below you can see the front view size comparison of Triangle Borea BR02 and Triangle Borea BR04 in scale.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Triangle Borea BR02 is approximately 482.2cm2 / 74.7inch2 and base area of the Triangle Borea BR04 is approximately 690.0cm2 / 107.0inch2. The Borea BR02 requires 30% less surface area than the Borea BR04 which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Triangle Borea BR02 weighs 4.87kg / 10.7lbs and the Triangle Borea BR04 weighs 8.60kg / 18.9lbs. This makes the Borea BR04 77% heavier than the Borea BR02.
